2 Type of ndustry: Type of product: PARTICLE SIZE CHARACTERIZATION REQUEST How was the materal made (ex. grndng )? What s the step of producton of powder (raw materal, etc)? What do you want to determne? Sze Shape Both What do you want to measure? Elementary Partcles Agglomerates In-State Powders What s the approxmate type of partcle sze dstrbuton? Monodsperse Polydsperse Whch knd of dameter do you expected for your results? D (1,0) : Dameter n Number D (2,1) : Dameter n Surface/Length D (3,2) : Dameter n Volume/Surface D (4,3) : Dameter n Weght/Volume N.B.: Standard results n partcle sze analyss by laser dffracton are explaned nto dameter n Weght/Volume or D (4,3). See at the end of the document the paragraph about the vocabulary. What knd of cumulatve curves do you want? Oversze Undersze N.B. : Standard cumulatve curves n partcle sze analyss by laser dffracton are n oversze. Whch values of dameters do you want for cumulatve curves? D10 D50 D90 Others :. N.B. : Please choose 3 dameters maxmum and one dameter at least. Standard cumulatve results (expressed n ISO norm) are D10, D50 and D90. Expected Sze: D50: µm Whch analyss method do you want? Fraunhofer Me Both If Me, please note the refractve ndex of partcle materal: Number of samples for ths product: Type of analyss: Dry mode Wet and Dry mode Wet mode Shape 2

4 Is your sample soluble? CHEMICAL PROPERTIES If Yes, enumerate the most commons solvents: Water Ethanol Other:.. Is the sample senstve to ph? Do you generally dsperse your partcles? If Yes, precse what you generally use: Dspersng Agent (ndcate t ) Ultra Sounds (tme:.s; Power: W, External/ Internal Probe) Condtons of Sample Analyss At recepton of the samples, the results wll be delvered wthn two weeks maxmum. If t s urgent, please contact CILAS drectly. All samples must be sent wth a Safety Datasheet, where are mentoned chemcal composton and cause uses. Wthout ths document, we won t be able to perform the analyss. For dry analyss, please supply a mnmum quantty of 50 grams of powder. CILAS wll not accept for analyss those materals whch are radoactve, Bohazards, for whch the applcatons laboratory s not equpped. 4

5 STANDARD OPERATURE PROCEDURE What s your carrer lqud? (non solvent lqud of the sample) Water Ethanol Other: Is the sample senstve to ph? What knd of Water do you generally use? Demneralsed Deonsed Regular water Whch dspersng agent do you use? HMP Decon Igepal Other:.. Do you use Ultra Sounds? Before analyss: s Tme durng analyss:.s Do you use an External Probe? Power:. W Tme:. S REQUESTED QUANTITY & SAFETY DATA SHEET Dry feeder: Lqud feeder: 100 grams/ sample mnmum 30 grams/ sample mnmum We remnd you that all samples must be sent wth a Materal Safety Data Sheet, where are mentoned chemcal compostons and cauton uses. Wthout ths document, we won t be able to perform the analyss. 5

6 VOCABULARY These defntons are used for the desgnaton and calculaton of all measurement parameters. The defntons are gven n alphabetcal order. All the equatons and the entre vocabulary secton refer to standard ISO DENSITY: The densty s the densty of your sample n g/cm 3. You wll need to enter the densty n the software to calculate parameters such as specfc surface. If you do not know the densty of your sample, you can measure t wth a specal nstrument. DIAMETER AT 10% and 90%: Ths s the dameter value for whch the cumulatve result s 10% or 90%. These two values gve you approxmatons of the smallest and the largest dameter contaned n your sample. MEDIAN SIZE (D50) : Medan sze s the dameter value for whch the cumulatve results are 50%. Ths means that half of the partcles n the sample are above the medan sze and half of the partcles are below the medan sze. DIAMETER IN VOLUME: The results provded by laser dffracton are n volume. Ths s due to Maxwell s equaton. By default, The Partcle Expert software wll gve you results n volume. The standard results are shown n De Brouckere mean dameter (also called D [4, 3], volume or mass moment mean). CILAS recommends usng ths knd of results to mprove the relablty of your measurements. The mathematcal formula used to calculaton the dameter n volume s: Where: n : number of partcles of class, d : dameter of class. D V = n d n d DIAMETER IN NUMBER: The dameter n number (also called D [1, 0] dameter) s an arthmetc average of the dameters. The mathematcal formula s as follows: 4 3 Where: n : number of partcles of class, d : dameter of class. D N = n d n DIAMETER IN SURFACE: The dameter n surface s also called D[2,1] dameter. The mathematcal formula s: Where: n : number of partcles of class, d : dameter of class. D S = 6 n d n d 2
